Eriez Magnetics: Test Cards

Eriez Magnetics' new free metal detection test cards contain a .0591 in. (1.5 mm) sphere of ferrous metal to test the sensitivity of metal detectors. Each card's metal sphere is embedded in a durable, laminated cover to provide easy use in a wide variety of wet or dry applications. This ferrous sample is readily detected by most Eriez E-Z Tec(R) metal detectors. Users simply place the laminated card in the line of the process and it should be detected as any tramp metal would be.
